Production of the spin partner of the X(3872) in e+e− collisions
We study the production of the spin partner of the X(3872), which is a D⁎D¯⁎ bound state with quantum numbers JPC=2++ and named X2(4012) here, with the associated emission of a photon in electron–positron collisions. The results show that the ideal energy region to observe the X2(4012) in e+e− annih...
